I recently had a customer who asked how VROC® technology measures viscosity compared to a rheometer that measures shear stress and also control shear rate. From the controls, the rheometer will then calculate viscosity. Similar to the rheometer, VROC® powered viscometers will measure the pressure drop to measure shear stress and use flow rates to control the flow. Essentially the ideas are parallel in the fact that VROC® measures the pressure drop and rheometers will measure torque so you will not need to readjust your expectations when working with VROC® technology.
At the 2020 Peptalk Conference that took place in San Diego, our Principal Scientist, Dr. Stacey Elliott, gave a talk regarding a thorough investigation of antibody therapeutics using viscosity results.
Working with various CROs and CDMOs, we've come to the question that many companies find themselves asking, "what is the cost of providing the wrong viscosity values to my customers and worse, having them submit the values for FDA approval?"
We are proud to announce our formal Rheology Forum which will take place from March 10 to March 12, 2020. The course will focus on the following:
Viscosity data for alcoholic beverages of various sugar and alcohol percentages was obtained using m-VROC®. The measured viscosity of these commonly consumed beverages was found to be dependent upon the amount of water, alcohol and sugar within the fluid. The viscosity of ethanol water solutions had a parabolic relationship as the amount of ethanol in solution increased. The addition of sugar to alcoholic beverages was also increased the viscosity of these fluids. Shear rate sweeps were performed to confirm Newtonian behavior of alcoholic beverage solutions over the
We would like to thank all of our wonderful customers, global partners, and collaborators for a wonderful 2019!
Our engineers are hard at work as they prepare for the upcoming webinar on Wednesday December 18, 2019! Try to guess what drinks are being measured on Wednesday (some clues in the images below!).
We will be at the upcoming MJ Biz Con conference in 2019. Come stop by to look at our canna-viscometers and also meet our Technical Specialists! We will be at Booth #C8309.
